Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial field of application) The present invention relates to connection of rolling surfaces of guide rails of an escalator.

(Prior Art) A guide rail for running steps of an escalator is used by connecting a plurality of guide rails one after another. At this time, if there is a step or a large gap on the rolling surface of the connecting portion where the rubber wheel of the step runs, the step rubber wheel is impacted and the ride comfort of the escalator is deteriorated.

Generally, the escalator is assembled at its installation location,
The installation and connection of a guide rail having an L-shaped cross section formed of a rolling surface on which the rubber wheel runs and a guide surface perpendicular to the rolling surface are also carried out during this installation and assembly. This connection work includes adjusting the length of the guide rail, welding for connection, finishing the rolling surface, etc., but this must be done under adverse conditions that the circumference of the escalator is extremely narrow as well as the inside of the narrow escalator.

In the conventional guide rail connection, as shown in FIG. 7, the back plate 3 of the rolling surface of the guide rail 1 is attached, the guide rails 1 and 1 are connected, and then the connection piece that fits in the guide rail notch that is provided in advance. 4 was attached to the back plate 3 with bolts to form the rail rolling surface of the guide rail connecting portion.

(Problems to be solved by the invention) However, in this method, since the guide rails 1 and 1 are connected by the back plate 3 and the connection piece 4 is the rolling surface, the number of parts is large and the connection and adjustment work is complicated. However, there have been drawbacks such as the notches of the rails and the shapes of the connecting pieces becoming complicated, and precision is required even during processing.

The present invention solves these problems, and provides a connecting piece that is simple in shape and easy to mount.

[Configuration of Device] (Means for Solving the Problem) The rolling surface at the tip of the guide rail is cut out into a rectangle having a width corresponding to the center line of the wheel width of the rolling rubber wheel. The side surface (plate thickness surface) of the rolling surface formed by cutting is attached with a mounting piece to increase the area (plate thickness width), and the side surfaces are connected by a connecting piece. The connecting piece is mounted and fixed flush with the remaining rolling surface so as to recreate the notched rolling surface.

(Operation) When the rubber wheel passes through the gap formed in the connection part by the connection piece performing both functions of connection and formation of the rolling surface, one side of the rolling surface of the rubber wheel is either the guide rail or the rolling by the connection piece. Since it runs on the moving surface, it does not fall into the gap. Since the connection piece is attached by screwing, the positioning can be adjusted.

(Embodiment) An embodiment of the present invention will be described with reference to FIGS. 1 to 3.

The tip ends of the guide rails 1 and 1 are notched in a rectangular shape with a width corresponding to the center line of the wheel width of the rubber wheel 5, and the mounting piece 7 is provided in order to increase the area of the notch surface, that is, the side surface 6 of the rolling surface. Is fixed flush with the side surface 6. The connecting piece 8 is rectangular, and the longer plate thickness surface is embedded in the notch so as to be flush with the remaining rolling surface of the notch, and the mounting piece (side surface 6, 6 of the rolling surface of the guide rail). Equivalent to), 7 and 7 are connected and fixed.

The upper surface of the connection piece forms a rolling surface instead of the notched rolling surface.

As another embodiment, the structure shown in FIGS. 4 to 6 may be used instead of the mounting piece 7.

That is, a rectangular mounting piece 9 extending below the rolling surface is fixed to the back surface of the guide surface of the guide rails 1, 1 with a countersunk screw 10, and the connection piece 8 is screwed thereto with a mounting piece 11. At this time, notches 12 corresponding to the rolling surface plate thickness of the guide rails are further provided at both ends of the connecting piece 8 to align the connecting piece 8 with the rolling surface 2.

Further, as shown in FIG. 4, the contact portion between the connection piece and the rolling surface of the guide rail is chamfered (shown by diagonal lines) so that the rubber wheel can be smoothly transferred.

[Advantage of Invention] According to the present invention, the rail length adjustment,
No welding or finishing is required, and the work of attaching the connecting piece is also easy. The guide rail notch shape is also simple.
